Abstract: The waste management system in the country is not proper, in order to provide a proper waste
management system we need to manufacture a machine that can sort the various waste constituents from
garbage which can be further processed and recycled to reduce the overall waste. So to achieve this, we are
manufacturing a waste segregator machine which is capable of separating wastes such as metals, non-metals,
plastic, etc. The design is the basic step for manufacturing of the machine if the design is proper and safe the
manufacturing goes smooth. We are manufacturing the machine to obtain the goal of separating the waste
which can be used by small scale as well as large scale industry effectively, which would directly add into
benefit for the society. The manufacturing the machine which would be easy to operate and simple in
construction. In short it would be affordable if produced in numbers.
Keywords –waste segregator machine, safe, effective manufacturing, affordable, waste management.
1. INTRODUCTION
Rapid population growth, urbanization and industrial growth have led to severe waste management
problems in the cities of developing countries like India. The large quantity of waste generated necessitates a
system of collection, transportation and disposal. It requires knowledge of what the wastes are comprised of, and
how they need to be collected and disposed. Recycling of waste, energy generation and employment
opportunities from waste management also have immense potential. However, it has been widely observed that
the Municipal Corporations in India do not have adequate resources or the technical expertise necessary to deal
with the problem. Successful waste management requires the participation of citizens, local governments, and
private entrepreneurs.
Waste segregation is the process in which the different constituents of waste are separated and to
achieve this waste sorting machine is used. This will help us to sort the various elements present in the waste
like plastics, metals, bricks and stones and other substances out from the garbage, to improve the reusing and
recycling of waste. At the same time, the separated waste materials can be further re-processed into useful
resources. So, the main purpose of the automatic waste sorter is reduction in processing and turning waste into
treasure.
1.1 PROBLEM DEFINITION
As the waste management system in India is not effective which leads to environment and health issues.
As India is price based market so the main obstacle in designing is the product cost, its compactness, efficiency
and also its reliability.

 Separating the different metals found in waste.
 Separating plastic from the waste.
 Recycling of waste
 Use of organic waste
 Disposal of harmful waste
 Separation of electronic waste
All the above mentioned problems are affecting the daily life of human being and results decrease in life.
Therefore above mentioned problems should be eliminated by designing a mechanical system.

Step 1: Market survey
This is basically done to how and where we can find parts like electric motor, L-Channel, conveyor
belt, bearing, blower, pulley, M.S plate, M.S Square tubing etc.to manufacture the machine and machining
operations required while manufacturing.
Step 2: Design
After completing the market survey we begin with the design of waste segregator machine. Here we
calculated the dimensions and tolerances of different parts of the system like conveyor belt, conveyor structure,
shaft, bearing, pulley, V-belt, roller, bag opener etc.
Step 3: Solid Model
According to our design calculation we made a solid model of our machine.
Fig.: Solid Model.
Step 4: Dummy Model
Dummy model is basically a replica of the solid model to check the feasibility of the machine. It was
built up of wood (acting as frame), plastic (acting as bins) and paper (acting as conveyor belt) to a suitable scale
proportionate to the actual one. After making this model, we got the idea and errors which was rectified and
necessary changes were done in the respective dimensions and design was finalized.
Step 5: Material Procurement
After knowing the technical parameters of the machine like type of motor to be used for driving the
machine, magnet for eddy current separator, bearing for giving a frictionless motion, blower for creation of air
flow, pulley for power transmission, conveyor belt for transmission purpose, bins for collection of waste, M.S
sheet for body of machine, L- channel for frame or stand, plastic roller for eddy current separator etc. we
procured material.

Step 6: Fabrication
Manufacturing the machine as per the dimensions and specifications mentioned on the engineering
drawing sheet begins here. Cutting operation was done by sawing, shearing, lathe turning, lathe milling etc.
Manual bending of M.S. sheet for bag opener was done, welding of the entire structure etc. work were
done.

The parts which were manufactured are as follows.
Conveyor:
Initially we started with the making of conveyor base which comprises of L-channels and 2 rollers
were mounted on either side of the conveyor.
Bag Opener:
At one end there will be a bag opener for opening the garbage bag which will be fed into it. There are
number of blades mounted on a shaft of bag opener at a predefined distance and orientation.
Eddy current separator
At the end of main conveyor belt, we placed a hollow roller made up of PVC pipe to get better results
and inside it there is a shaft passing through the hollow roller and the shaft is concentric to the roller. The roller
and the shaft are moving at different speeds with the help of two different induction motors.
Roller is the core component of eddy current separator composed of 20 pairs Neodymium permanent
magnets around by the PVC drum mounted on the shaft. The permanent magnets were alternately configured by
S-N-S direction.
Step 7: Assembly
All the parts which were manufactured are finally assembled according to the design specifications.
Step 8: Testing
Now, the machine was tested and some minor changes were made to achieve our objectives of
manufacturing the machine and then results were recorded multiple times.
3. WORKING
First the plastic bag containing different constituents like plastic, paper, ferrous, non-ferrous, wood, etc.
are dropped into the bag opener. The bag opener is only used to open the plastic bag. After opening the plastic
bag all the waste present in it will fall on the conveyor.
The conveyor will move all the waste towards the blower and all the materials like light plastics; paper
will be blown off by the blower. The blown material will be collected in a collecting bin. The remaining waste
will move towards the end of the conveyor, here we have our eddy current separator.
Here with the help of eddy current separator, ferrous (due to attraction of the magnets) and non-ferrous
materials (due to wedge or repulsive force created by the magnets) are separated apart. Due to the wedge action,
non-ferrous metal will be thrown off and collected in respective bin and because of the magnetic effect of the
eddy current separator the ferrous metal will stick to surface of the conveyor belt and will be collected in
respective ferrous bin.

blower
Separating ferrous & non-ferrous
metals using eddy current separator
Collecting waste in their respective
bin
Insert waste into the hopper

The remaining waste like hard plastic, wood, etc. will be collected in between the ferrous and non-
ferrous bin. By this way all the constituents will be separated from the waste.
4. RESULTS AND DISCUSSION
Based on the eight step methodology implemented in the previous chapter, the results obtained are
listed below:
Result Table
Type of solid waste Total Waste (in %) Waste segregated (in %)
Paper 11.7 11.5
Light plastic (polythene bags) 4 3.9
Ferrous materials 35 35
Non-ferrous materials 22.5 20
Solid Plastic 15 15
Wood 11.8 11.8
Total 100 97.2
5. CONCLUSION
With drastic change in urbanization and rise in industries, India is facing voluminous waste
management challenge. There is no adequate plan or system to sort, recycle or reuse the waste being generated.
So we have successfully manufactured a machine which is capable of segregating different constituents present
in the waste like paper, plastic, ferrous, non-ferrous, wood etc. Our machine is efficient, compact in size and
most importantly affordable by any small scale industry or even by any housing society. Thus, by active citizen
participation one can built small but effective waste segregating machine which is capable of segregating the
waste.
1. Separation of ferrous, non-ferrous, plastics, wood etc. from the waste.
2. Designing a compact and affordable machine.
3. The recycled waste can be further sent for recycling.
4. Decreasing the chances of hazardous condition for land and labour.
